Add to Quote


Monitor indoor environments and occupancy levels with the Elsys ERS Eye. This smart sensor enables you to record a variety of environmental factors including:

  • Temperature
  • Humidity
  • Light
  • Motion
  • Occupancy

With a discrete form factor, the Elsys ERS Eye can be ceiling mounted in areas such as meeting rooms, offices, and classrooms. Combining a range of sensors in one device, the ERS Eye enables you to optimise room use and comfort levels.

Utilising LoRaWAN® technology, the Elsys ERS Eye connects to a nearby LoRaWAN® gateway which then transmits data by a LoRaWAN® Network. Recorded data can then be visualised on your chosen IoT platform, enabling you to optimise room efficiencies.
